New Delhi: Supreme Court has dismissed the review plea of Nirbhaya case convict Akshay Kumar Singh's. He is one of the four men convicted in the 2012 Nirbhaya gangrape and murder case.  The convict has now sought time to file mercy plea.

The court said, "We do not find any grounds to review the issue. Same averments raised cannot now be considered." The hearing on Singh's review plea was delayed by a day on Tuesday (December 17) after Chief Justice of India SA Bobde recused himself from hearing the review plea.

CJI SA Bobde recused himself from the case because his nephew had represented Nirbhaya in a court earlier.  The review petitions of the three other convicts, Mukesh, 30, Pawan Gupta, 23, and Vinay Sharma, 24, had been dismissed earlier.

Of the six accused of Nirbhaya's rape and murder, four were convicted.

Among those convicted, Ram Singh committed suicide and a juvenile was released after spending three years in a reform home.

The Patiala House Court's hearing of the petition filed by Nirbhaya’s parents, scheduled at 2pm, on December 18, will depend upon the Supreme Court's verdict.

The 23-year-old was gang-raped and brutally assaulted on the intervening night of December 16-17, 2012 inside a moving bus in south Delhi by six persons before being thrown out on the street. She died on December 29, 2012 at Mount Elizabeth Hospital in Singapore. One of the six accused in the case, Ram Singh, allegedly committed suicide in Tihar Jail.

Reacting to the Supreme Court’s decision to reject the review petition, Nirbhaya's mother said she is happy with the verdict and is awaiting the Patiala court’s decision.
